Give each installer the same information: heater type and capacity, location, existing connections, building access, and photos of the installation area. Ask whether the quote includes the unit, valves, pipes, wiring changes, mounting, testing, and removal of old equipment. Clarify whether a site visit is needed before a firm price can be given.
Confirm who supplies the heater, what product warranty applies, and whether installation workmanship has separate terms. Require approval before extra materials or work are added. Browse local service listings on KobStore, then verify the provider’s experience and written quote directly.
